Upside Down Labs BioAmp v1.5 (2023 Edition) - EMG Biopotential Amplifier Module
The BioAmp v1.5 is a standalone, single-channel biopotential amplifier designed for non-invasive EMG (electromyography) signal acquisition. It operates directly from a 9V battery and outputs amplified muscle signals via a standard 3.5mm audio jack for recording on mobile devices, laptops, or audio software like Audacity, requiring no external microcontroller.
Features
- Standalone EMG amplifier requiring no Arduino or microcontroller for signal sampling.
- High input impedance (10^7 Ω) for stable, low-noise recording from surface electrodes.
- Fixed gain of ~200x amplifies microvolt-level muscle signals to line-level audio output.
- Simple 3-electrode (positive, negative, reference) setup for quick, non-invasive measurements.
- Complete kit includes PCB, 1m cable, AUX cable, 9V snap, gel electrodes, and muscle band.

The BioAmp v1.5 is an open-source hardware module engineered for accessible biopotential measurement. It features a high-performance instrumentation amplifier front-end with a fixed gain of approximately 200x, optimized for the typical amplitude range of surface EMG signals. This design ensures clean amplification while maintaining a high common-mode rejection ratio to minimize environmental electrical noise.
Powered by a standard 9V battery (7-9V input range), the module outputs a conditioned audio signal compatible with any device featuring a 3.5mm microphone/line-in jack. This plug-and-play architecture simplifies integration into educational, research, and hobbyist projects focused on human-computer interaction, biomechanics, and physiological monitoring, eliminating the need for complex ADC circuitry or programming.
